Heat treating is a process of heating or cooling metals and is used to alter their properties in order to obtain the desired shape and structure such as brittleness, hardness, and softness. The steps for achieving these things are consistent with all heat treatment processes. Heat treatment techniques include annealing, tempering, hardening, quenching, stress releasing and normalizing. Different metals respond to treatment at different temperatures. One of the remarkable things about this process is that it is applicable to conditions where cooling and heating are completed for the purpose of altering properties. The heating and cooling often occur incidentally during other manufacturing processes such as hot forming or welding. The most commons application is metallurgical. Heat treatment is frequently connected with expanding the quality of material; however it can be utilized to adjust certain manufacture-ability targets, for example, enhanced machining, form-ability, and restore malleability after a cool working operation.
